The company is the same one that was managing a New York construction site where a crane partially collapsed during Superstorm Sandy in October.

The collapse Tuesday at the University of Technology Faculty of Engineering and Information Technology construction project happened two weeks after union officials shut the site down over concerns about diesel fuel leaking from the crane, the Morning Herald reported, citing union official Brian Parker.

It was not immediately clear if that reported leak had anything to do with Tuesday's collapse, but firefighters believed diesel fuel was involved in the fire, the Morning Herald cited Turner as saying.

The fire and collapse drew hundreds of gawkers onto the streets to record the incident with cell phone cameras.

The company said it was working with authorities and unions to investigate the incident.

In late October, gale-force winds from Superstorm Sandy caused a construction crane to collapse atop what will become an upscale apartment high-rise.

The collapsed New York crane was operated by Pinnacle Industries. Lend Lease, the construction manager on the project, said the crane had been inspected days before the storm and was determined to be properly placed for hazardous weather.
